STUDY ON SEISMIC RESPONSE OF BRIDGE GROUP PILES-SINGLE PILLAR PIER AT LIQUEFACTION SITE BASED ON LARGE-SCALE SHAKING TABLE MODEL TEST

摘要

Taking 2 × 2 low cap group piles-single pillar pier generally used in bridge engineering and three layers soil as the subject to investigate, large scale shaking table test is performed. Based on it, scale modeling design, loading scheme, acceleration and dynamic strain of piles and pillar in the test are discussed in detail.
